Description

Technical Field

[0001] This utility model relates to the field of quilt cover hemming technology, and more specifically, to a novel quilt cover hemming device. Background Technology

[0002] A quilt is a type of bedding product. It is a rectangular piece of fabric with an area large enough to cover the human body and is generally used to keep warm during sleep. A quilt usually consists of a quilt cover and a quilt insert. Due to the material, the quilt cover and quilt insert may shift during the process of being put on, which will affect the user experience of the quilt.

[0003] In response, Chinese patent application number CN202223147181.X discloses a duvet cover fastener, including a locking mechanism and a silicone needle. The locking mechanism and the silicone needle are movably connected. A base is provided at the tail end of the silicone needle. The locking mechanism includes a lock cover, a first lock element, and a second lock element. A limiting platform is provided inside the lock cover. The first lock element is located at the bottom of the lock cover. The second lock element is slidably disposed inside the first lock element. The first lock element has a first through hole. The second lock element has a second through hole. The sliding trajectory of the second lock element has a first sliding position and a second sliding position. When the second lock element is in the first sliding position, the first and second through holes are aligned and allow the silicone needle to extend or retract. When the second lock element is in the second sliding position, the first and second through holes are offset by a certain distance, clamping the inserted silicone needle. The purpose of this utility model is to provide a duvet cover fastener with a simple structure and reliable safety.

[0004] The device uses silicone needles to prevent people from being pricked, but in actual use, the silicone needles are directly exposed on the bed. When the user turns over in bed, it can cause injury to vulnerable areas such as the eyes and ears, which limits the use of the device.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a new type of quilt cover locking device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of quilt cover locking device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A novel quilt cover edge-locking device includes: a first fixing block, the top surface of which has a movable groove, and a second fixing block installed on the upper side of the first fixing block;

[0009] The bottom surface of the first fixing block is provided with a pressing groove, the upper and lower surfaces of the second fixing block are provided with rotating grooves, and the bottom surface of the second fixing block is provided with an insertion hole.

[0010] A locking structure is installed on the first fixing block and the second fixing block. The locking structure includes a pressing plate, which is slidably installed on the inner side of the movable groove. A pointed screw is fixedly connected to the top surface of the pressing plate, and a spring is sleeved on the outer side of the pointed screw. A pointed rod is fixedly connected to the edge of the pressing plate. A rotating block is rotatably installed on the inner side of the rotating groove, and a threaded sleeve is fixedly connected to the bottom surface of the rotating block.

[0011] The edges of the first fixing block and the second fixing block are bonded with annular rubber sleeves.

[0012] Preferably, the first fixing block and the second fixing block cooperate with each other, and the movable groove communicates with the inside of the pressing groove.

[0016] Preferably, the annular rubber sleeve protrudes from the top surface of the first fixing block and the bottom surface of the second fixing block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the first fixing block and the second fixing block are respectively placed on both sides of the quilt. By pressing the pressing plate in the pressing groove, the pressing plate can be driven to move in the movable groove. The pressing plate squeezes the spring and drives the pointed screw and pointed rod to protrude from the surface of the first fixing block, which can penetrate the quilt cover and the quilt core. Rotating the rotating block can drive the threaded sleeve to rotate. The threaded sleeve can be threaded to the upper end of the pointed screw, which can limit the pointed screw on the upper side, so that the first fixing block and the second fixing block are clamped together towards the quilt, which can be stably installed on the quilt. The pointed screw and the pointed rod cooperate with each other to lock the edges of the quilt cover and the quilt core. The operation is convenient. When the first fixing block and the second fixing block are separated, the pressing plate can be retracted into the movable groove under the action of the spring, and the pointed screw and the pointed rod can be retracted into the surface of the first fixing block, so that the surface of the first fixing block is smooth and without protrusions, which can prevent the first fixing block and the second fixing block scattered on the bed from injuring people, thereby improving the safety of the device.

[0019] 2. In this utility model, an annular rubber sleeve is glued to the edges of the first fixing block and the second fixing block. The annular rubber sleeve can undergo elastic deformation when the first fixing block and the second fixing block are in contact with the quilt surface, and fit the quilt surface, so that the transition between the first fixing block and the second fixing block and the quilt is smooth, and the soft quilt is prevented from wrinkling, so that the edges of the first fixing block and the second fixing block are exposed, causing the quilt to snag or injure people.
